Java – calculates the number of “trues” of N Boolean values

Boolean a,b,c,d;

Boolean a,b,c,d;

I want to count the number of trues. Each result should have its own associated action Maybe it's like this:

int result = getResult(a,d);
switch (result) {
    case 0: break;
    case 1: break;
    case 2: break;
    case 3: break;
    default: break;
}

Is it nice to know how to write the getResult method body? In this example, I only use four, but it should be able to expand to more Boolean values You are welcome to continue in any other way

Solution

Write a variable method?

int getResult(boolean... vars) {
    int count = 0;
    for (boolean var : vars) {
        count += (var ? 1 : 0);
    }
    return count;
}
